Specification of Letters Patent.

Application filed August 18, 1910. Serial No. 577,816.

To all whom it may concern:

Be it known that we, CLAYTON T. VVHIP- ILE and HERBERT A. MOODY,citizens of the United States, residing, respectively, at Glens Falls,in the county of Warren, and at Hudson Falls, in the county ofWashington, State of New York, have invented certain new and usefulImprovements in Globe- Lifters, of which the following is aspecification.

This invention relates to globe lifters for tubular lanterns.

Lifters have heretofore been made consisting of a piece of bent wirepivoted to the lantern tubes, one of which is provided with acatch-plate attached thereto, which engages the crank or other part ofthe lifter to hold the globe up after it is raised.

The object of the present invention is to provide an improvedconstruction with respect to the lifter, by means of which the use ofthe separate catch-plate is avoided, and the cost of making andattaching the same is saved, the arrangement being such that the liftercrank will engage the seam of one of the tubes, for the purpose ofholding the globe up, with a further engagement, if desired, to hold theglobe down.

Several embodiments of the invention are illustrated in the accompanyingdrawings.

Figure 1 is a front elevation of part of a tubular lantern, with theglobe lowered; Fig. 2 is a detail in side elevation showing the positionof the lifter, when the globe is lowered; Fig. 3 is a similar elevationshowing the position of the lifter when the globe is raised; Figs. 4 and5 are details of a modification, with the lifter in lowered and raisedpositions respectively; Figs. 6 and 7 are similar views of anothermodification.

Referring particularly to Figs. 1, 2 and 3 of the drawings, 6 indicatesthe lantern globe, 7 the plate on which-it rests, and 8 the side tubesof the lantern, these tubes being formed of two semi-circular blanksunited by longitudinal scams 9. These parts are old and well known. Thetubes have pivot bosses 11 perforated to receive the cranked ends of thelifter wire 12 which extends across between the tubes and is bent aroundthe burner collar in the usual manner and has an additional projectingpart or finger 13 which bears under the globe plate 7 to lift the globewhen the lifter Wire the standing part and extended outwardly to formthe pivot. One branch of the wire forming the handle is also bentlaterally to produce a finger 15, the construction and arrangement beingsuch that this finger rests or bears against the inner seam 9 of theadjacent tube. The pressure of the finger 15 against the seam is ayielding one, incident to the amount of bending and the spring of thewire, the spring effect tending tov press the handle toward the tube,and the length of the finger 15 is such that when the handle is swungdown to lift the globe in the usual manner, the spring action causes theend of the finger to snap and engage behind the seam, as shown in Fig.3, thereby holding the globe in raised position. lower the globe it isnecessary to apply force enough to spring the handle inwardly until thefinger 15 will pass the rib formed by the seam. Then the handle may beswung up and the globe let down accordingly. By reason of thisconstruction it will be seen that the seam answers the purpose of acatch-plate, whereby the labor and expense of an attached catch-plate isavoided, the seam serving all the functions thereof; and the pressure ofthe finger 15 against the seam, when the globe is lowered, is sufiicientto prevent accidental movement of the lifter.

The modified form shown in Figs. 4 and 5 has the same advantage withrespect to omission of the catch-plate. In this form the wire formingthe handle 14 of the lifter is bent to substantially a triangular shape,with two of the arms or branches thereof resting against the seam withspring pressure, and the seam is provided with upper and lower notches20 and 21, located above the pivot, and so arranged that when the handleis raised and the globe lowered the lower branch 14 of the handle willengage in the notch 21, as shown in Fig. 4, and when the handle is swungdown to lift the globe the upper branch 14 of the handle will engage inthe notch 20, as shown in Fig.

5, thereby serving to hold the globe in either raised or loweredposition.

In the modified form shown in Figs. 6 and 7 the handle 30 of the litteris bent to press against the seam on the tube which has upper and lowernotches 20 and 21*, into which the handle catches, respectively, when itis raised or lowered. In this form the hinge for the lifter is producedby a strap 31 on the side of the tube, and the cranked handle of thelifter may be located on the outer side of the tube.

It will be observed that in all these forms no separate catch-plate isnecessary, and the invention may be embodied in various other forms, nolimitation in this respect be ing implied.

0 claim:

1. The combination with a tubular lantern frame having an upright sidetube with a longitudinal projecting seam thereon, of a globe lifterpivoted on the frame and having a crank handle adjacent the tube, saidhandle having a laterally extending projection bearing against andengageable with the seam to hold the litter in adjusted position.

2. The combination with a tubular lantern frame having a side tube witha projecting seam, of a pivoted globe-lifter provided with a crankhandle having a projecting linger bearing against the seam andengageable therewith to hold the litter in raised position.

In testimony whereof we afliX our signatures in presence of twowitnesses.
